The number of locusts (l) t days after an infestation is given by the equation
l = 5t2 + 10t + 100
The area of grass left (a) in m3 is given by the equation a = 500/ l
Use composite functions to determine the rate of change of the area of grass on the sixth day.
Explain why there is a limit to the time over which these equations would be realistic.
Dear Classified. You are right. Thank you for correcting us.

There is an error with your answer... The final answer is actually
(-175 / 578)... To get the answer you got you must have added an extra
zero to "340". I played with the calculations to see how you got your
answer. If you keep "340" as "340", you'll get (-175 / 578). :)
